Waterborne epoxy coating compositions with self-emulsifying amine hardeners

Polimery 2006, No 11-12, 817


Summary

Three waterborne varnish compositions and epoxy coatings prepared of liquid bisphenol A - based epoxy resin „Epidian 6” and self-emulsifying hardeners (amine adduct type) were investigated. The effects of hydrophilicity of the hardeners used on the technological properties (fluidity, pot life, drying time - Table 1) and useful ones (adhesion, scratch resistance and water uptake - Table 2) of the coatings on the steel substrate, after curing at room temperature, were determined.


Key words: waterborne epoxy compositions, self-emulsifying hardeners, epoxy coatings, useful properties
